IMPROVEMENT IN WRENCHES.

Specification forming part of Letters Patent No. 193.566, dated July 24, 1877 March 20, 1877.

. marked thereon, which form a part of this specification, and in which Figure 1 is a side elevation. Fig. 2 is an end Vl-eW. Fig. 3 is a cross-section on the line indioated by :varin Fig. 2.

Similar letters of reference indicate corresponding parts in all the figures.

This invention relates to wrenches; and it consists in the Construction and arrangement of parts hereinafter more fully shown and specified.

In the drawing, A A are 'the two arms or sides of my improved wrench. They are oined together at a so as to form the base or stock B, which is squared off at the bottom, so as to enable the removable handle C to be conveniently adjusted.

The ends of arms A A are shaped so as to form the head F, the inside of which and of arms A is squared off, as shown at b, Fig. 2, so as to readily clasp the nut which is to be operated upon.

The manner in which I operate the arms A A is illustrated inFigs.1, 2, and3, whereE is a clasp or sleeve, which is slid upon the arms until it abuts upon the head F. This sleeve has a thumb-screw, Gr, which operates against one of the arms A, thus forcing it against the other as far as desired.

application filed The arms AAmust have sufiicient elasticity to spring apart automatically when the pressure of thumb-screw G is removed.

From the foregoing description the operation and advantages ot' my improved wrench will be readily understood. Its construction is simple and cheap, and it can be used in many diferent ways and for a multitude of purposesfor instance, as a bit-lengthener. It can also be conveniently used as a handle for various kinds of tools.

It may be operated either by the removable handle 0, hereinbefore mentioned, or by means of a brace.

An important advantage of my improved wrench is thisthat the clasp E, being arranged to slide upon the arms A A, the capacity of the wrench is not limited to nuts small enough to be inserted between the jaws when the clasp rests against the head F. When larger nuts are to be operated upon, it is only necessary to' slide the clasp down toward the stock B, when the jaws may be spread sufficiently to receive nuts of a larger sze.

Having thus described my invention, I claim and desire to secure by Letters Patent- The combination of arms A A, uniting at a, so as to form the stock or base B, with the sliding adjustable clasp or sleeve E, having thumb-screw G, substantially as and for the purpose herein shown and specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses,

JOHN H. SNYDER.
